Over the weekend, the rear end was probed with a stethoscope both on jack
stands in 4th at 30mph and while driving around with one rear seat removed.
We never really heard the growl on the jackstands. All the bearings seemed
to emit a nice whir including the OD rear.
We did notice a clickety clack noise that seemed to come from the diff and
that there was almost 1/4 inch rotational slack at the pinion flange while
my spare diff is more like .030!
While driving with the rear seat removed, we did hear the growl similar to
the normal 1st gear whine only of a different lower pitch. Most evident when
starting up a hill in 2nd. I don't hear it in 1st, but maybe the normal
whine masks it. I also think I hear it in 3rd under a low rpm load.
So maybe it is a transmission issue that I didn't hear on the jackstands
because I was in 4th direct?
